Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Skull bones that are external bones of the cranium; form the dorsolateral walls of the cranium. They are large and well developed in dogs and cats - but small in horses and cattle.






2. Skull bones that are the bones of the ear; three pair of bones in the middle ear that transmit sound wave vibrations from the tympanic membrane to the inner ear.






3. The joint movement that increases the angle between the two bones.






4. Secondary areas of growth in bones developing by the endochondral method; areas of bone development located outside the main portions of the carilaginous bone templates in a developing fetus.






5. A hinge joint in which one articular surface swivels around another; the only movements possible are flexion and extension.






6. The first - most cranial sternebra.






7. The shoulder blade; the most proximal bone of the thoracic limb. No bony connection exists between the scapula and the axial skeleton.






8. The visceral bone in the heart of cattle that helps support the valves of the heart.






9. Small bones shaped like cubes or marshmallows; an example are the carpal bones.






10. The large metacarpal and metatarsal bones (III) of the horse.






11. An arthrodial joint in which two flat articular surfaces rock on each other; the carpus is an example.






12. The 'forearm' region of the thoracic limb.






13. Skull bones that are external bones of the cranium; form the lateral walls of the cranium - contain the middle and inner ear structures - and are the skull bones that form the temporomandibular joints with the mandible.






14. Process on the cranial end of the second cervical vertebra (axis) that fits into the caudal end of the first cervical vertebra (atlas).






15. The visceral bone in the penis of dogs that partially surrounds the penile portion of the urethra.






16. One of two concave - half moon - shaped - cartilaginous structures on the proximal surface of the tibia that help support the condyles of the femur.






17. A skull bone that is one of the internal bones of the face; forms part of the nasal septum.






18. The main - weight - bearing bone of the lower leg; forms the stifle joint with the femur proximal to it and the hock with the tarsus distal to it.






19. The healing tissue between the ends of a fractured bone that is eventually replaced by true bone as the fracture heals.






20. An immovable joint; also known as a synarthrosis. The bones are firmly united by fibrous tissue; includes the sutures between the skull bones.






21. Small cavities within the matrix of some connective tissues - such as cartilage and bone - within which cells are contained.






22. The large hole in the occipital bone through which the spinal cord exits the skull.






23. A skull bone; one of the external bones of the face. It is the lower jaw - the only movable skull bone - and contains all of the lower teeth.






24. Skull bones; external bones of the face. These two bones make up most of the upper jaw and house the upper canine teeth - if present - and all of the cheek teeth.






25. Skull bones that are part of the external bones of the cranium; located on the dorsal midline just rostral to the occipital bone.






26. The type of bone formation whereby bone grows into and replaces a cartilage model; this is the method by which most bones form in a developing fetus - starting with cartilage 'prototypes' that are gradually replaced by bone. It is also the means by w






27. The eardrum; a paper - thin connective tissue membrane that stretches across the opening of the external ear canal into the middle ear.






28. The vertical portion of the mandible located at its caudal end; site where jaw muscles attach to the mandible.






29. A space within a skull bone that is an outpouching of a nasal cavity; depending on the species - these are found within the frontal bones - maxillary bones - sphenoid bones - and ethmoid bones.






30. A bone whose shape does not fit into the long bone - short bone - or flat bone categories. Bones either have characteristics of more than one of the other three shape categories or have a truly irregular shape. Includes vertebrae and sesamoids.






31. Mature bone cells located in lacunae.






32. A slightly movable cartilaginous joint - such as the pubic symphysis.






33. The breastbone; a series of rodlike bones called sternebrae that form the floor of the thorax.






34. The area of a bone that joins the head with the main portion of the bone.






35. A skull bone; an internal bone of the cranium. This single bone is located just rostral to the sphenoid bone and contains the cribriform plate.






36. One of countless tiny channels through the matrix of bone that bring blood in from the periosteum to the haversian canals in the centers of the haversian systems. The haversian systems run lengthwise in long bones while these canals come in at right


37. A depressed or sunken area on the surface of a bone; usually occupied by muscles or tendons.






38. The bones of the neck portion of the spinal column.






39. Blood cell production; usually occurs in red bone marrow.






40. A skull bone that is one of the internal bones of the cranium; forms the floor of the cranium and contains the pituitary fossa - a depressin that houses the pituitary gland.






41. The smallest and most medial of the three pairs of bones that make up the pelvis; forms the cranial portion of the floor of the pelvis.






42. Skull bones that are part of the external bones of the face; form the bridge of the nose or the dorsal part of the nasal cavity.






43. The bone in the neck region that supports the base of the tongue - the pharynx - and the larynx - and aids the process of swallowing. It is usually referred to as a single bone - but it is composed of several portions of bone and cartilage.






44. The visceral bone in the snout of swine that strengthens it for the rooting behavior of pigs.






45. A joint in which the bones are united by cartilage; also called an amphiarthrosis. Only a slight rocking motion is permitted between the bones.






46. The cartilaginous joint (amphiarthrosis) that unites the two halves of the pelvis ventrally. Also called the pubic symphysis.






47. Long bones of the axial skeleton that form the lateral walls of the thorax; dorsal portions are made of bone and form synovial joints with the thoracic vertebrae. Ventral portions are cartilage.






48. A joint motion whereby the distal end of an extremity moves in a circle.






49. The outer layer of a bone that is composed of compact bone.






50. The joint between the pelvis and the sacrum that joins the pelvic limb to the axial skeleton.
